Haughty and egotistical
cosmetic surgery droid 11-H8 grew to despise his vapid, dull-witted clientele,
and decided to remove more from them than cellulite. He extracted secrets from his quasi-anaesthetized patients, and began a campaign of blackmail, extortion, and thievery...

up in his faceplate, as his clients were some of The Empire's richest,
mightiest, and most unforgiving plutocrats.

By day, isothropes are feral Pure Human derelicts who haunt the wastelands... but beneath the Mutant Future's shattered full moon, they transform into corrupted creatures akin to those of Ancient mythology.

Isothropes glow a scintillating neon, and their eyes burn with blue radioactive rage. Their blackened, cracked skin sloughs off in sheets. Tainted blood seeps from every orifice. Isothropes are always clad in the tattered remnants of radiation suits.

Isothropes are immune to radiation, toxins, and disease, and all weapons inflict only half damage [to simulate their hyperactive healing]. The creatures spread their infectious metamorphic condition as per the lycanthropy disease [Labyrinth Lord Core Rules, p. 86].
